How to Care for Immortal Flower
As a widely loved succulent plant, the immortal flower is highly praised for its unique fleshy leaves and super strong vitality. Mastering scientific maintenance methods not only keeps the plant in a full state but also promotes the blooming of star-like flowers. This article will systematically explain the complete knowledge system of home cultivation, from environmental control to pest and disease prevention.
Five Key Points for Caring for Immortal Flower
1. Substrate Mixing and Potting Techniques
It is recommended to use a mixture of decomposed leaf soil, coarse river sand, and perlite in a ratio of 3:2:1, with 50g of bone meal mixed per cubic meter. When repotting in spring and autumn, keep 1/3 of the protective soil, and choose a new pot with a diameter 3-5cm larger than the original pot, with a 3cm layer of ceramic stones at the bottom for drainage.
2. Intelligent Lighting Management Plan
Receive full sunlight in spring and winter, and use a sunshade net with 40% shading rate from 10:00 to 15:00 in summer. Supplement with 2 hours of 450nm blue light from LED lights daily, which can increase leaf thickness by over 15%.
3. Temperature and Humidity联动 Control
Setting a day-night temperature difference of 5-8℃ can stimulate flowering, maintaining 22-25℃ during the day and not lower than 15℃ at night. Turn on the circulating fan when the air humidity is above 60%, and spray with 800 times solution of 百菌清 weekly to prevent diseases.
4. Precise Water and Fertilizer Management Cycle
Use the "dry-wet alternation" method, watering thoroughly when the potting soil is 1/3 lighter. Apply N-P-K=10-15-10 water-soluble fertilizer every 15 days during the growing period, and switch to a 2000 times solution of potassium dihydrogen phosphate during the budding period.
Advanced Guide for Propagating Immortal Flower
1. Efficient Cutting Method in Four Steps
Select semi-woody branches and keep 3-4 pairs of leaves. Dip the cut end in 1000ppm IBA rooting powder, insert into a mixture of vermiculite and perlite (1:1), maintain a constant temperature of 25℃, and achieve a rooting rate of 90% within 14 days.
2. Key Techniques for Seedling Cultivation
Soak seeds in 40℃ warm water for 6 hours before sowing, then cover with 0.5cm of red jade soil. Use bottom heating to maintain a substrate temperature of 28℃, combined with 12 hours/day of supplemental lighting, to increase the germination rate to 75%.
Eco-friendly Pest and Disease Control System
Rotate monthly sprays of matrine and azadirachtin to prevent aphids, and use 75% alcohol cotton swabs to physically remove scale insects promptly. For the early stages of powdery mildew, use a 500 times solution of baking soda plus a 1000 times solution of dishwashing liquid, sprayed consecutively for 3 days for effectiveness.
Through this article's systematic maintenance plan, combined with regular observation and recording, the immortal flower can maintain a vigorous growth state throughout the year. It is recommended to establish a maintenance log, record each watering and fertilizing data, and gradually form a personalized breeding model, making this "eternal flower" truly a permanent beautiful feature in your home.
